Describes the specific matching of base pairs. This matching occurs because the structure of one base precisely fits with, and bonds to, another specific base. In DNA adenine and thymine are complementary and form a base pair, as do cytosine and guanine. When pairing occurs between DNA and RNA, adenine and uracil are complementary, and cytosine and guanine are complementary.

Single-stranded DNA produced from an RNA template (usually mRNA) by reverse transcriptase in vitro. It lacks the introns present in corresponding genomic DNA. It is most commonly made to use in PCR to amplify RNA (RT-PCR).

with respect to nucleic acids, complementary means that one strand of nucleic acid (DNA or RNA) can pair with and serve as a template for its complementary strand; complementary strands are related by the base-pairing rules: A pairs with T or U and C pairs with G.

Referring to two nucleic acid sequences or strands that can form a perfect base-paired double helix with each other; also describing regions on two interacting molecules (e.g., an enzyme and its substrate) that fit together in a lock-and-key fashion.

A property of DNA whereby each nitrogenous base pairs with another particular base (A with T and G with C); two complementary single strands have nucleotide sequences that enable their bases to pair up; see Figure B-8.

Colors which lie directly opposite each other on the color wheel are as unlike one another as they can be. The two colors selected contrast with each other to make a bold statement (ie: red & green, blue & orange, etc.)

a color that's opposite another on the color wheel. Red and green are complementary; so are blue and orange. Complementary colors intensify each other, making each other "pop." Use them to create focal points, to highlight a particular area of the garden.

Complementary is the term for two identical periodic signals where one signal is electrically inverted from the other. Example of single channel electrically inverted. Complementary signals are typically generated by inversion of the electrical output from a single channel.

Output circuit for which also the inverted signals are outputted (e.g. Channel A and Channel A). Electrically, the 1/0 levels are transmitted as voltage differences between two lines. In this way the information signal (the difference) remains pure as in general interferences are interspersed equally on both lines.
